If I have to start keeping track of a second dimension of time, I’m not sure my planner is going to be sufficient. Of course, I can always claim that I was late for work and app’ts due to fact that I am going by the wrong dimension of time. It’ll be cool.
I wonder what the negative axis of time looks like in particle land. It’s like a tachyon that not only reacts instantaneously, but BEFORE you actually perturb the item under test. Causation goes out the window. Most of this stuff probably only existed in the first few seconds of the universe anyways, so it probably will have no real significance.
